CONCLUSION: OVX plus STZ induced more serious bone impairment than OVX alone, which involves the IGF-1R/β-catenin signaling axis in the pathogenesis. This may provide a potential target for treatment of postmenopausal diabetic osteoporosis. PMID: 33000666 [PubMed - as supplied by publisher]

Semin Musculoskelet Radiol 2020; 24: 337-354 DOI: 10.1055/s-0040-1708823Radiologic imaging is crucial for diagnosing and monitoring rheumatic inflammatory diseases. Particularly the emerging approach of precision medicine has increased the interest in quantitative imaging. Extensive research has shown that ultrasound allows a quantification of direct signs such as bone erosions and synovial thickness. Dual-energy X-ray absorptiometry and high-resolution peripheral quantitative computed tomography (CT) contribute to the quantitative assessment of secondary signs such as osteoporosis or lean mass loss. Magnetic resonance ima...

Authors: Ohashi K, Ishikawa T, Hoshii A, Hokari T, Suzuki M, Noguchi H, Hirosawa H, Koyama F, Kobayashi M, Hirosawa S, Sugiyama K, Mitobe Y, Yoshida T Abstract L-carnitine administration was reported to improve sarcopenia in patients with cirrhosis. However, the amount of evidence from previous studies is not sufficient. The present study aimed to clarify the effect of levocarnitine (L-carnitine) administration on body composition in patients with chronic liver disease (CLD). In the present study, 85 patients with L-carnitine administration and 87 control patients were enrolled and divided them into two groups, the...

Abstract OBJECTIVE: The goal of this study was to compare different recognized definitions of osteoporosis in patients with degenerative lumbar spine pathology undergoing elective spinal fusion surgery to determine which patient population should be considered for preoperative optimization. METHODS: A retrospective review of patients in whom lumbar spine surgery was planned at 2 academic medical centers was performed, and the rate of osteoporosis was compared based on different recognized definitions. Assessments were made based on dual-energy x-ray absorptiometry (DXA), CT Hounsfield units (HU), trabecular b...

AbstractThe surgeon general of the USA defines osteoporosis as “a skeletal disorder characterized by compromised bone strength, predisposing to an increased risk of fracture.” Measuring bone strength,Biomechanical Computed Tomography analysis  (BCT), namely, finite element analysis of a patient’s clinical-resolution computed tomography (CT) scan, is now available in the USA as a Medicare screening benefit for osteoporosis diagnostic testing. Helping to address under-diagnosis of osteoporosis, BCT can be applied “opportunistically” to most existing CT scans that include the spine or hip re...

Conclusions: As NaF PET/CT becomes more popular in evaluating skeletal calcium metabolism (as shown by the measurement of osteoporosis), advancing technology such as total-body PET/CT scanners should be used to take complete advantage of this imaging modality. We believe that future, well-powered studies are needed to prove this prediction, and detail the far-reaching benefits today-body PET/CT scanners can have for osteoporotic patients.

46Objectives: Traditionally, obesity is believed to be protective against osteoporosis. However, recent accumulating evidences suggest that visceral obesity increases the risk of osteoporosis and obesity-driven dysfunctional metabolic activity in visceral adipose tissue (VAT) is considered as a possible underlying mechanism for the development of obesity-related osteoporosis. 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) is an established method to assess the degree of VAT metabolic activity. We aimed to investigate the predictive role of VAT metabolic activity evaluated by 18F-FD...

AbstractPurpose of ReviewThis review discusses imaging modalities for fracture repair assessment, with an emphasis on pragmatic clinical and translational use, best practices for implementation, and challenges and opportunities for continuing research.Recent FindingsSemiquantitative radiographic union scoring remains the clinical gold standard, but has questionable reliability as a surrogate indicator of structural bone healing, particularly in early-stage, complex, or compromised healing scenarios. Alternatively, computed tomography (CT) scanning enables quantitative assessment of callus morphometry and mechanics through ...
